UNITED STATES PATENT FlElQEm ALFRED B. HUTCI-IINSON, OF BROOKLYN, N. Y., ASSIGNOR TO THE GLEN COVE MACHINE COMPANY, (LIMITED,) OE SAME PLACE.

WOOD-=PLANING MACHINE.

SPECIFICATION forming part of Letters TPatent No. 396,934, dated January 29, 1889.

Application filed September 2'7, 1888. Serial No. 286,534. (No model.)

To all 1071 0110 it may concern.-

Be it known that l, ALFRED l-l. .HULCIIINSON, of Brooklyn, (Green Point,) in the county of Kil'lgs and State of New York, have invented a certain new and useful Improvement in \Vood-llan ing Machines, ol which the following is a specification, ret'erenee being had to the accompanying drawings.

To enable others skilled in the art to make and use my invention, 1 will first describe it with reference to the d ra wings, and afterward point out its novelty in claims.

Figure l in the drawings represents a plan view of those parts of a planing-n1achine necessary to illustrate my invention. Fig. .2 is an elevation of the same parts as viewed from the right side oi Fig. l. Fi represents a vertical section in the line of Fig.1.

Similar letters oi. reference designate corresponding parts in the several figures.

A designates the upright spindle ot' one of the iiiatelienl'lmuls l) of a planing-machine. This spindle is supported in the usual or any suitable manner in bearings in the matcherleg-0t the machine, which it is not col'lsidered necessary herein to show or describe. The matcher-head l; is represented as furnished with cutters 7.), such as are conunonl y used.

(1 designates what is commonly known as the hcad-plate, which is intended to be supported in the usual manner and secured to the top of the watcher-leg. in the upper part of this head-pl ate is re n'esimt-ed a ci rcular recess, 0, which receives the lower part ot the matcherhead B, so that the cutters l) stand above the upper surface of the said plate.

.D designates the arm of a chip-breaker, pivoted bya pin, a, to the head-plate (l and having the greater portion of its length arranged below the upper surface of the said plate and outside of the outer nutrgin ol said plate, but having ,that end farthest from the pivot a projecting upward above the said plate, as shown at (Z in Figs. 1 and 2,110 carry the nosepiece 1), which acts in conjunction with the cutters to break the shavings into chips. This nose-piece is secured to the chip'breaker by means of a bolt, 0.

The above described construction of the chip-ln'ealun' and arrangement ol the same, in combination with the cutter-head and head plate, are not intended to' be claimed. herein,

but constitute the suliject-matter of n1yapplication for United States Letters Patent, Serial No. 382,993, filed August 17, 1888.

E designates a guide for the edge of the board bolted to a guide-carrier, E, which is bolted to the hezul-plate by a bolt, f, in the usual manner.

G designates a shaving-hood consisting of a tube througlnvhich the chips are blown away by the blower-like action produced by the cutter-head and cutters in their rotation. This sharing-hood is turi'iished on one side with a slotted lug, g, through which it is bolted by a bolt, 9, to the head-plate in such manner as to be adjustable toward and from the center of the axis of the clutcr-spimlle to permit a proper adjustment of the said hood relatively to the cutters. The arrangementof the chipbreaker arm below the upper surface of the head-plate (1 permits the shaving-hood to cocupy a position over the said arm without either interfering with the other and allows the entrance of the said hood to be brought very close to and exactly opposite the edges of the cutters b.

The nose-piece D of the chip-breaker is provided with a long tongue, (1, which projects backward into the recei VillgdllOllllll of the shaving-hood G, as shown in l. and 3, for the purpose of directing the chips into the shaving-hood as they are broken off by the chip breaker and cutters. Thistongue d has its face which is toward the cutter-head eccentric to the axis of said head, as shown in. Fig. 1, in order that the chips, which are subject to the centrifugal current of air produced by the cutters, may not be driven against said face, but may pass freely by it into the shaving-hood G.

\Vhat I claim as my invention, and desire to secure by Letters Patent, i.s

1. The combination, in a wood-planing ma chine, with a side cutter-head, a fixed headplate below said cutter head, and a chip breaker a portion of which is below the level. of the upper surface of said plate, of a shay ing-hood secured to said plate and lying over the said portion of the chip-breaker, substam tially as herein described.

2. The combination, in a wood-planing machine, with the side cutter-head and its outters, and a shaving-hood opposite the said cutters, of a chip -breaker provided with a tongue which enters the mouth of the said hood for the purpose of guiding thereinto the shavings or chips produced by the said outters, substantially as herein described.

3. The combination, in a wood-planing machine, with the side cutter-head and its outters and a fixed head-plate below the said whichis below the level of the said head- I plate, but the nose of which is above the said head-plate, a shaving-hood which is attached to the head-plate and which overlies the portion of the chi p-breaker below the said plate, and a tongue attached to the chip-breaker and entering the mouth of the shaving-hood, substantially as and for the purpose herein set forth.
